Patent EP-0392569-A3 (EP)
Title: Digital phase adjustment
IPC: H04N9/455
Filed: 1986-04-07
Abstract: A method of generating an electrical signal representative of 
subcarrier to horizontal sync (SC-H) phase of a composite video signal 
that includes a horizontal sync pulse and a colour burst is performed by 
sampling the video signal under control of a clock signal having a 
frequency equal to an integral multiple of the burst frequency. The two 
samples taken immediately before and after the sync point of the 
horizontal sync pulse is determined and the samples are interpolated to 
determine the value of a first angle representative of the phase within 
the clock cycle at which the sync point occurred. The value of a second 
angle is determined which is representative of the phase within the 
subcarrier cycle at which a third sample is taken and the required 
electrical signal is generated using the values of the first and second 
angles and the relationship between the clock frequency and burst 
frequency.

Title: Diagnostic kit, primer composition and their use for replication or detection of nucleic acids
IPC: C12Q1/68
Filed: 1990-04-09
Abstract: Amplification, replication or detection of a predetermined target nucleic acid can be carried out using a unique primer composition. This composition comprises an aqueous mixture of a first oligonucleotide primer which is substantially complementary to a first specific nucleic acid sequence of the target, but which is suspected of having one or more mismatches with the target at or near its 3 min  end. Also included in the composition is one or more additional primers which are complementary to a nucleic acid sequence of the target. This sequence is either: (i) inclusive of only a portion of the first specific nucleic acid sequence, (ii) immediately adjacent to the first specific nucleic acid sequence, or (iii) removed from the first specific nucleic acid sequence by one or more bases, but which additional primer is capable of forming a primer extension product complementary to the first specific nucleic acid sequence. These composition components can be supplied as part of a diagnostic test kit which can include other reagents if desired.

Title: New process for disposing of the residues deriving from the processes of synthesis of chlorinated hydrocarbons
IPC: A62D101/22
Filed: 1990-06-05
Abstract: The disposal of chlorinated pitches is carried out by means of a process which consists of two treatments with an alkanol, which are carried out in cascade. Such treatments cause the precipitation to take place of the suspended matter, which is then caused to settle, is separated and is pyrolized, whilst the supernatant is distilled in order to separate the alkanol, which is recycled back to the process, and the other organic components, which are sent to further uses.

Patent EP-0385560-A3 (EP)
Title: Compressor for heat pump and method of operating said compressor
IPC: F25B13/00
Filed: 1990-02-08
Abstract: A compressor (01), e.g., a scroll type compressor for a heat 
pump including a bypass passage by way of which the high 
pressure side (14) of the compressor is communicated with a 
compression chamber (24) in which a compression stroke is carried 
out is disclosed. The compressor (01) further includes 
opening/closing means (31) so that when it is required that the 
compressor is operated at a high efficiency, the bypass 
passage is closed and when it is required that the 
compressor is operated with a high level of ability, the 
bypass passage is opened so as to allow high pressure gas to 
be introduced into the compression chamber (24) in which a 
compression stroke is carried out whereby the gas is 
compressed again.

Title: Windscreen wiper assembly for a motor vehicle
IPC: B60S1/34
Filed: 1990-01-16
Abstract: A windscreen wiper assembly, for use as a 
passenger windscreen wiper assembly in a motor vehicle, 
comprises a drive crank (24) secured to one 
end of a spindle (20) rotatably mounted in a bore 
housing (22) on a rigid support frame (16), the other 
end of which spindle (20) is secured to one end of a 
first link (12), the other end of which is pivotally 
connected to one end of a wiper arm (18). A second, 
cranked link (14) is pivotally mounted at one end to a 
bore housing (46) on the support frame (16), and is 
pivotally connected at the other end to a bore housing 
(34) on the wiper arm (18) at a predetermined distance 
from the pivot point between the first link 
(12) and the wiper arm (18). Reciprocatory movement of 
drive crank (24) produces a similar reciprocatory 
movement of link (12), which causes wiper arm (18) to 
oscillate about the pivot point between the second link 
(14) and the wiper arm (18), which oscillation, 
in turn, causes reciprocatory movement of second link 
(14) about its pivot point with support frame (16). 
The combined movement of the wiper arm (18) thus 
produced results in a wiper blade attached to a free 
end of wiper arm (18) sweeping out an asymmetric 
wiping arc on a windscreen which is preferentially 
distorted outwards relative to a conventional radial 
wiping arc that said wiper blade would sweep out if the 
wiper arm (18) were directly pivoted to the support 
frame (16) in a conventional manner.

Title: High density connector for an ic chip carrier
IPC: H01R12/71
Filed: 1990-03-23
Abstract: A high density connector assembly for an IC chip 
carrier (10) includes a stack of spacer plates (30) 
having apertures (32) which form chambers for holding 
planar contact members (22) therein. The stack of 
spacer plates (30) are sandwiched between a lower 
reference plate (34) and an upper reference plate (36) 
which have precisely located apertures (42, 44) 
communicating with the chambers for precisely 
positioning contact portions of the contact 
members (22) with respect to contact pads (14, 18) on 
the IC chip module (10) and a printed circuit board 
(12). The plates (30, 34, 36) are preferably formed of 
a dielectric coated metal material to provide a ground 
shield around the contact members (22) to prevent cross 
talk therebetween.
Patent EP-0400979-A3 (EP)
IPC: H04M9/08
Filed: 1990-05-30
Abstract: An echo canceler-suppressor speakerphone arrangement effectively addresses 
the limitations of regeneration and reverberant return echo inherent in the 
design of speakerphones. The tendency for regeneration is eliminated by 
employing adaptive echo cancellation in the receive path of the speakerphone 
arrangement to cancel speakerphone talker echo across a hybrid and thereby 
reduce the local loop gain to below unity. And the generation of a reverberant 
return echo to the far-end party is avoided by employing adaptive echo 
suppression in the transmit path of the speakerphone arrangement. Near-full 
and full duplex operation are regularly achieved since the receive path remains 
open at all times and transmit path has its gain reduced only to the level 
necessary to suppress excessive reverberant return echo.

Title: Variable length codeword packer.
Inventor: DEROVANESSIAN HENRY
IPC: H04B1/66
Filed: 1994-03-23
Abstract: A variable length codeword packer (Fig. 3) communicates codeword data in successive m-bit bytes. A binary sum is accumulated (86) indicative of a total number of codeword bits received over time. A byte pointer (90) is derived from at least one most significant bit of the binary sum. A bit pointer (92) is derived from a plurality of least significant bits of the binary sum. A first data storage array (20) has a plurality of m-bit first storage bytes and is responsive to the byte pointer for storing received codeword data in the first storage bytes. A second data storage array (22) has a plurality of m-bit second storage bytes and is responsive to the byte and bit pointers for filling the second storage bytes with codeword data from the first data storage array (20). m-bit bytes of codeword data (25) are output from each filled second storage byte to provide successive m-bit bytes of codeword data. The use of a multistage approach in packing variable length codewords substantially reduces the complexity as compared to single stage designs. <IMAGE>

Filed: 1994-12-14
Abstract: An adjunct processor (16) sends an end-of-address indication, such as a
pound sign, along with the address, such as an extension number, to which a call is
to be transferred, to a switching system (12, 14). The sent end-of-address indication
causes the switching system to not accept further addressing information from the
caller (10), thus preventing the caller from modifying the sent address and effecting
the transfer of the call to an address different from the sent address, such as a long-distance
telephone number. Perpetration of adjunct-assisted toll fraud is prevented
thereby.
